That's very true.
Apart from Bitcoin, only projects that innovate can and will survive. There are a handful of projects that innovate, one of them is Gadgetcoin - that's why I support it in the first place, not to mention that because of the innovation and real world use cases, this is the very few projects that can actually make money in long term. Even I have doubt that Ethereum or NXT will make money in long term, because there is no assurance at all, more precisely it is very unlikely that for example any country will switch its land register to a new technology by using the Ethereum's smart contracts, so I am not sure where the money is going to come from to Ethereum or NXT in the long term. In the meantime, at least Gadgetcoin/Gadgetnet has a realistic chance to make money by addressing real world use cases such as empowering Internet of Things (connected) cameras.
